The self defense umbrella 100 (hereinafter invention) is a safety device. The invention 100 is configured for use with a person. The invention 100 forms a defensive shield 101 that blocks and deflects an offensive projectile 191 directed at the person using the invention 100. The invention 100 comprises a shield 101 and a control system 102. The shield 101 forms a physical barrier that blocks and deflects an offensive projectile 191 directed at the person using the invention 100.

The control system 102: 1) captures images of the environment of the person using the invention 100; 2) determines the GPS coordinates of the person using the invention 100; 3) transmits the captured images and the GPS coordinates to an appropriate authority 172; 4) illuminates the environment of the person using the invention 100; and, 5) operates a defensive firearm 128 incorporated into the invention 100. Each invention 100 further comprises an interlocking mechanism that allows a plurality of inventions 100 to be interlocked to expand the volume of the protected space relative to the space protected by any individual self defense umbrella. The appropriate authority 172 is discussed in greater detail elsewhere in this disclosure.

The shield 101 is a vertical barrier structure. The shield 101 is a collapsible structure built in the structure of an umbrella. The shield 101 forms a physical barrier that blocks and deflects blows and projectiles directed at the person using the invention 100. The shield 101 is a paraboloid structure. The shield 101 is further defined with a focal point 194, a concave surface 195, and a convex surface 196. The focal point 194 is the mathematical focal point 194 of the paraboloid structure of the shield 101. During normal use of the invention 100, the concave surface 195 of the shield 101 is proximal to the person using the invention 100. The convex surface 196 is the surface of the paraboloid structure that is distal from the person using the invention 100.

As shown most clearly in FIG. 9, the paraboloid structure of the shield 101 forms a reflective surface that deflects an offensive projectile 191 that is directed at the person using the invention 100 such that: 1) the incident angle 192 of contact of the offensive projectile 191 equals the reflected angle 193 of the deflected offensive projectile 191; and 2) the vector formed by the reflected angle 193 deflects the offensive projectile 191 in a direction away from the focal point 194 of the paraboloid structure of the shield 101.

Designing the paraboloid structure of the shield 101 in this manner creates a safe zone for the person using the invention 100 when the focal point 194 of the shield 101 is placed directly between the person using the invention 100 and the source of the offensive projectile 191.

The shield 101 comprises a canopy 111 and a frame 112.

The canopy 111 is a structure that absorbs and deflects the kinetic energy of the offensive projectile 191 in a direction away from the safe zone of the shield 101. The canopy 111 is a sheeting structure that forms the surface of the paraboloid structure when the invention 100 fully deploys. The canopy 111 attaches under tension to the frame 112.

The frame 112 is a titanium structure that holds and maintains the canopy 111 in the shape of the paraboloid structure when the invention 100 fully deploys. The physical structure of the frame 112 closely follows the physical structure of an umbrella. Any modifications to the frame 112 relative to a standard umbrella frame are intended to reinforce the frame 112 to withstand the kinetic energies to which the shield 101 is subjected. The frame 112 comprises a plurality of ribs 141, a plurality of stretchers 142, a runner 143, a center shaft 144, and a handle 145.

The canopy 111 comprises a plurality of panels 131. Each individual panel selected from the plurality of panels 131 comprises a plurality of textiles 132, a plurality of deflection plates 133, and a magnet 134. The plurality of textiles 132 comprises an outer textile layer 181, one or more protective textile layers 182, and a base textile layer 183.

The canopy 111 is assembled from the plurality of panels 131. The plurality of panels 131 is a collection of individual panels of a roughly triangular shape. Each individual panel selected from the plurality of panels 131: 1) is designed to absorb energy from the offensive projectile 191; and, 2) is designed to deflect the offensive projectile 191 in a direction away from the focal point 194 of the shield 101. Each individual panel selected from the plurality of panels 131 is a composite textile.

The plurality of textiles 132 comprises a minimum of three sheeting layers. Each sheeting layer contained within the plurality of textiles 132 is designed to: 1) absorb energy from the offensive projectile 191; 2) deflect the offensive projectile 191; and, 3) contain the plurality of deflection plates 133 within the individual panel. In the first potential embodiment of the disclosure, each of the plurality of textiles 132 comprises a commercially available poly-para-phenylene terephthalamide (CAS 25035-37-4) based textile.

As shown most clearly in FIG. 6, the plurality of deflection plates 133 are assembled in the manner of a mosaic in the sense that smaller individual plates are placed next to each other. The mosaic structure of the plurality of deflection plates 133 maximizes the surface area protected by the plurality of deflection plates 133 within the individual panel while allowing the individual panel to remain flexible within the overall structure of the canopy 111.

The magnet 134 is a neodymium magnet. The magnet 134 attaches to the individual panel along the section of the individual panel that forms the outer perimeter of the canopy 111. The magnet 134 of a first instantiation of the invention 100 is intended to attach to the magnet 134 of a second instantiation of the invention 100. By interconnecting the magnets 134 of two separate instantiations of the invention 100, multiple instantiations of the invention 100 may be joined to create a safe zone of increased size relative to the safe zone that is achievable by a single instantiation of the invention 100.

The canopy 111 is assembled by joining two panels to each rib selected from the plurality of ribs 141. Each of the plurality of ribs 141 joins a first panel selected from the plurality of panels 131 to a second panel selected from the plurality of panels 131.
